The lot is accepted if no item out of 5 samples show the presence of
Staph. aureus
in 1g,
where the concentration is higher than 10.000 CFU/g. The lot is rejected in the opposite
case.

Sampling and Decision:
Annex I: Microbiological Criteria, Table: Microbiological Criteria, Point of application: at
source, during production and end product. Assuming a log normal distribution and an
analytical standard deviation of 0.25 log cfu/ml, the sampling plans would provide 95%
confidence that a lot of water containing a defined not acceptable geometric mean
concentration of specific microorganisms would be detected and rejected based on any of
five samples testing positive.

Recommended Methods Of Sampling For The Determination Of Pesticide
Residues For Compliance With MRLS
Sampling:
The minimum number of primary samples to be taken from a lot is determined from Table
1b. The primary samples must contribute sufficient material to enable all laboratory samples
to be withdrawn from the bulk sample. The position from which a primary sample is taken in
the lot should preferably be chosen randomly but, where this is physically impractical, it
should be from a random position in the accessible parts of the lot.
The primary samples should be combined and mixed well, if practicable, to form the bulk
sample. The minimum size of each laboratory sample is given by Table 4, 1.2. The analytical
sample should be comminuted, if appropriate, and mixed well, to enable representative
analytical portions to be withdrawn. The size of the analytical portion should be determined
by the analytical method and the efficiency of mixing.
Decision:
The lot complies with a MRL (Pesticide Residues in Food and Feed, Codex Pesticides
Residues in Food Online Database, FAO and WHO 2013) where the MRL is not exceeded
by the analytical result(s). Where results for the bulk sample exceed the MRL, a decision
that the lot is non-compliant must take into account: (i) the results obtained from one or more
laboratory samples, as applicable; and (ii) the accuracy and precision of analysis, as
indicated by the supporting quality control data.
